I can't seem to understand how to import a polyfill

[mikealche]

Hello!
First, thanks for this amazing project! It looks really awesome and I'm loving it!!

However, I'm having lots of troubles setting up adonisjs' websocket client library

In the documentation says

The module build requires the regenerator-runtime polyfill (add it via Babel).

But how do I do that?

Right now I'm trying in .babelrc

{
    "presets": [
      [
        "next/babel",
        {
          "preset-env": {},
          "transform-runtime": {},
          "styled-jsx": {},
          "class-properties": {}
        }
      ]
    ],
      "plugins": ["@babel/plugin-transform-regenerator"]
}

But that throws me an error saying:
Cannot find module '/Users/mike/batcave/workolam/frontend/.next/server/static/development/pages/_document'

So, how should I import it?

Question number 2: once I resolve that... how do I import the library so it only loads in the client?

I would really like to be able to use nextjs as a frontend with adonisjs as a backend. But this configuration error is tearing me down :(

If anyone could indicate me what steps I should follow, that'd be amazing!
Thanks in advance

regenerator-runtime is already included in Next.js, so there's nothing to add really.

Thank you very much Tim! For this, and for all the work you do!
